This is a program for further development of the MUSTANG millimeter-wave camera which has been developed for use on NSF's Green Bank Telescope (GBT). The main science goal is to obtain deep, high-resolution observations of galaxy clusters via the Sunyaev-Zeldovich effect (SZE), a decrement in the cosmic microwave background strength as photons pass through a cluster and scatter off of the high temperature intra-cluster gas and out of the line of sight. Broader impacts of the work include the training of undergraduate and graduate students in instrumentation development. Members of the team are actively involved with public outreach in the Philadelphia area including star parties, the Philadelphia science festival and mentoring in low-performing schools.The upgrade is called MUSTANG-2, and will increase the number of detectors from 32 to 223. The sensitivity of the detectors will be greatly enhanced as well. Maps of the SZE in galaxy clusters at 90 GHz with the 100-meter Green Bank Telescope will provide a combination of unprecedented mapping speed, resolution, and sky coverage which will unlock the full potential of these complex objects.

这是一个用于进一步开发野马毫米波相机的程序，该摄像头已开发用于NSF的绿色银行望远镜（GBT）。 主要的科学目标是通过Sunyaev-Zeldovich效应（SZE）获得对星系簇的深度高分辨率观测，随着光子通过簇并散布在高温内部内部内部气体和视线线之外，宇宙微波背景强度的降低。 这项工作的更广泛的影响包括在仪器开发方面对本科生和研究生的培训。 该团队的成员积极参与费城地区的公共宣传活动，包括明星派对，费城科学节和在低表现的学校中进行指导。升级称为Mustang-2，并将大大增强探测器的敏感性。 带有100米绿色银行望远镜的90 GHz星系簇中的SZE地图将提供前所未有的映射速度，分辨率和天空覆盖范围，这将释放这些复杂物体的全部潜力。
